The invention of air conditioners (ACs) has made life easier, giving us a sigh of relief from the scorching heat. There was a time when installing an air conditioner was considered a luxury but today, it has become more of a necessity. In fact, modern ACs do more than just making the environment pleasant; they reduce the possibility of asthma attacks, keep insects and parasites away, and prevent electronic appliances at home from overheating, reduce the risk of dehydration and heatstroke, and much more.
All said and done, choosing the right air conditioner for your home is very important. That will allow for proper cooling of the room as well as help in ensuring that there is no excess energy consumption, thereby helping you save cost and keep your house energy-efficient. Along with improving the quality of air, the AC’s reliability and durability are equally imperative. Once you have identified the options available that meet your criteria, the next important consideration is the size of the air conditioner.
The first thing that you must keep in mind while selecting an air conditioner is the size of your room. If you buy an air conditioner that is too small compared to the size of the room, the unit would struggle to achieve the intended level of air conditioning. On the other hand, if you buy an air conditioner that is too large, then it would cool the room too quickly without removing the humidity from the air, which will leave you cold and clammy. This is why it is essential to keep the size of the room in mind while choosing the right air conditioner.
The summer season in India can many a time get extreme. This is especially true for mid-summers during which it becomes an ordeal to stay in the urban environment. The monsoon season too is extreme at times. However, the weather conditions in India vary from region to region. So, choose the air conditioner keeping the climate and weather condition of your region in mind. Research about the air conditioners and the technologies on offer, compare them online and only then seal the deal.
Another thing that you must keep in mind is the energy efficiency of the air conditioner. The Bureau of Energy Efficiency assigns a rating to all the air conditioners in the form of stars. ACs with the highest star rating are among the most energy-efficient ones that will help in saving money on your electricity bill tremendously. Hence, check for the air conditioner size that prioritises energy savings.
Lastly, checking the tonnage of the air conditioner is a factor that you should not miss out on at any cost. The size of the room, the climate, the number of heat sources, and so on sum up the simple rules of thermodynamics. Knowing the capacity of the air conditioner is important as it will help in deciding better not only in terms of cooling but also in your budget.
In addition to this, check the direction of your window, exposure to direct sunlight, elevation or floor of the residential area, other appliances in the room, and preference of the air quality when choosing an air conditioner for your room.
There are two ways of calculating the tonnage, namely: –
Here, you have to multiply the length and breadth of the room in feet and then take the square root of the answer. Divide the answer (after the square root) by 10. The resultant is the desired tonnage required for your room.
For example: Consider a room that is 15 feet wide and 20 feet long.
Multiplying length and breadth i.e. 20 x 15 = 300
Square root of 300 = 17.32; divide 17.32/10 = 1.73
So, for a 300 sq. ft. room, you will need an AC with a tonnage of 1.73
In this, you need to multiply the length, breadth, and height of the room in feet. Divide the answer by 1000. The resultant is the required tonnage.
For example: Consider a room that is 10 feet long, 15 feet wide with a height of 20 feet.
Multiplying length, breadth, and height = 10x15x20 = 3000 c.u. feet
Now dividing 3000 c.u. feet by 1000 = 3000/1000 = 3
So, for a 3000 c.u. feet room, where the height is double the length, you need to get a 3-ton AC.
